When you need the highest quality wirewound axial
terminal resistors available, choose Ohmite’s 90
Series resistors.
They are manufactured by a unique process that
molds the vitreous enamel over the resistive ele-
ment, helping to ensure consistent dimensions.
This uniformity permits 90 Series resistors to be
mounted in clips, creating a heat-sinking benefit (see
next page).
The durable vitreous enamel coating, which is totally
lead free, permits the 90 Series resistors to maintain
a hard coating while operating at high temperatures.
Mechanical integrity is enhanced by the all-welded
construction.
